DISCUSSION
THE REST OF TODAY THROUGH WEDNESDAY...
SCATTERED (30-60% CHANCE) SHOWERS AND THUNDERSTORMS WILL BEGIN
OVER THE WEST THIS AFTERNOON, MOVING EAST BEFORE GRADUALLY
DISSIPATING LATE THIS EVENING. A FEW STORMS MAY BECOME STRONG TO
SEVERE, WITH STRONG WINDS OF 60+ MPH. ANY STORM WILL BE CAPABLE OF
PRODUCING SMALL HAIL AND POCKETS OF HEAVY RAIN. SPC HAS ISSUED A
MARGINAL RISK (LEVEL 1 OF 5) FOR MUCH OF WESTERN AND CENTRAL
MONTANA AND A SLIGHT RISK (LEVEL 2 OF 5) FOR A PORTION OF WESTERN
MONTANA.
CONDITIONS WILL REMAIN HOT AND DRY AHEAD OF THE SHOWERS AND
THUNDERSTORMS MOVING IN. TAKE CARE NOT TO CAUSE A SPARK!
FOR FRIDAY AND SATURDAY, AN UPPER LEVEL TROUGH APPROACHES FROM
THE PACIFIC NORTHWEST BEFORE SLIDING ACROSS NORTHERN MONTANA
SUNDAY INTO EARLY MONDAY. MOISTURE WILL BE ELEVATED, WITH PWATS
AROUND 140-180% OF NORMAL, ALLOWING SCATTERED TO NUMEROUS (40-80%
CHANCE) SHOWERS AND THUNDERSTORMS TO CONTINUE IN THE AFTERNOON AND
EVENING HOURS THROUGH THE WEEKEND, WITH POTENTIAL FOR SHOWERS TO
LINGER INTO THE OVERNIGHT HOURS (20-50% CHANCE). A FEW STORMS MAY
BECOME STRONG TO SEVERE, ALTHOUGH WHICH DAY WILL HAVE THE MOST
POTENTIAL WILL DEPEND ON THE TIMING OF THE BULK OF THE ENERGY
ASSOCIATED WITH THE TROUGH MOVING THROUGH. THIS WILL BE SOMETHING
TO KEEP AN EYE ON. ADDITIONALLY, TEMPERATURES WILL GRADUALLY COOL
THROUGH THE WEEKEND, DECREASING TO LOW 70S TO LOW 80S BY SUNDAY.
GOING INTO NEXT WEEK, CONDITIONS LOOK TO REMAIN UNSETTLED UNDER
UPPER LEVEL SOUTHWEST FLOW. THIS WILL KEEP HIGHS NEAR TO SLIGHTLY
ABOVE NORMAL (GENERALLY 80S) AND ALLOW A LOW DAILY CHANCE (10-40%)
FOR AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS TO CONTINUE.
